Question 1. Are there other unrecorded children of Elisha and Mary Leavitt?

Background: Daughter Celia (bapt. 1758) was added to this family from Abington First Church baptism records, 1750-1774. Her parentage to Elisha and Mary Leavitt is inferred from the Abington church and from her daughter's middle name (Leavitt), not from any direct documentary evidence — we still need to verify these are the correct parents to associate her with.
